Manufacturers of 3D TV sets are about to suffer a loss. As the hype of 3D moved from the movie screen into the home, its potential was poorly judged and ill timed. This blog has commented on the looming disaster since inception only to fall on deaf ears .... or in this case blinded marketers. The 3D lemmings are approaching the cliff and will undoubtedly go over.

It was a novelty. A fad. They come and go as did the 3D craze in the 1950s. History will repeat itself .... this time in spades.

What follows is a partial lift from an article by TV Predictions.com focusing on 10 (just 10?) reasons why 3D TV will not make it. For a full read, follow this link.

1. 3D TV Interrupts Your Viewing ExperienceYou can't watch 3D TV for more than a minute without finding your eye focusing on individual elements of the screen rather than the picture as a whole. For example, if you're watching a 3D presentation of a college football game, you find yourself watching the player whose display best showcases the 3D effect. It's natural; you know you're watching 3D so your mind and eye tend to focus exclusively on the strongest 3D elements of the picture.

That makes for an interesting minute or two, but it's not why people watch television. They want to take in the entire picture; to be absorbed by it; to let it take over their entire thinking process so they can relax and lose themselves in what they are watching. 3D doesn't allow for that; it constantly interrupts you to check out some 3D effect. After awhile, you almost forget what's happening on the field or in a movie. If you're a Chicago Cubs fan, that could be a plus. But for most viewers, it's a strong negative.

2. It Makes You Sick Doctors have estimated that up to 20 percent of the population will get headaches, dizziness or even nausea while watching 3D.

Steven Nusinowitz, an associate professor of ophthalmology at the Jules Stein Eye Institute in Los Angeles, tells CNN that 3D glasses have a polarized filter that separate two images, thereby enabling the 3D effect. However, the doctor adds that the separation occurs so quickly that your brain may have difficulty accepting it.

"The movie is telling you 'Hey, I'm moving around in this scene,' but your vestibular system is telling you, 'I'm not moving anywhere,' and that disconnect will make you feel sick, for some people," Nusinowitz said.

TV makers even warn consumers in their 3D TV manuals that they could get sick while watching 3D; they advise that you should take off the glasses every 15 minutes or so.

How many consumer products have ever been successful with the masses if their makers had to tell you they might make you sick?

3. Millions of People Just Bought New TVsBecause of the federally mandated Digital TV transition in 2009, millions of Americans bought a new TV to ensure they could continue watching when their local stations switched from analog to digital. Even in good times, people tend not to buy a new TV every few years or so; they buy one with the intention of keeping it for years.

And we're now in an economic morass; will people sacrifice the rent money for a 3D TV? When they probably have a TV in their living rooms that's not even three years old?

4. People Hate the 3D GlassesJust about every objective consumer study has found that people hate wearing those 3D goggles while watching 3D TV. It's an uncomfortable experience, particularly if you wear prescription glasses or contact lenses with different prescriptions for each eye. The 3D apologists say that 3D sans the glasses is in the works, but most analysts say it will take years before the technology is ready

5. 3D TV Is Not HDTVThe 3D apologists like to say that High-Definition TV had a slow ramp-up to success. Well, that's true. But people didn't buy HDTVs in the early days because the sets were cost-prohibitive, with some medium-sized ones costing up to $10,000.

In contrast, the cost of a 3D TVs is just slightly more than a comparably-sized 2D HDTV. People aren't buying them because they cost too much; they aren't buying them because they don't want them.

In addition, when someone saw a HDTV in person, he wanted it, at least eventually when the price came down. The picture added to your viewing enjoyment because it made you feel like you're were there; the picture was that realistic. But 3D is the antithesis of realism; it's a tech trick designed to jolt a response from the viewer. But the response doesn't last long and it's ultimately unsatisfying. Unlike HDTV, watching 3D TV is not relaxing; it's jarring.

As for the "No Glasses Required" sets due to launch .... don't buy the hype. A small 20" set will run you back about $2800 and you will need to "learn" how to watch TV.
